E7-10339. Public Water System Supervision Program Revisions for the State of Indiana

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Notice of tentative approval.

SUMMARY:

Notice is hereby given that the State of Indiana is revising its approved Public Water System Supervision Program. Indiana has revised the following rules: Arsenic, Radionuclides, and Long Term 1 Enhanced Surface Water Treatment Rule.

EPA has determined that these revisions by the State are no less stringent than the corresponding federal regulations. Therefore, EPA intends to approve these revisions to the State of Indiana's Public Water System Supervision Program. Any interested party may request a public hearing. A request for a public hearing must be submitted by June 29, 2007, to the Regional Administrator at the EPA Region 5 address shown below. The Regional Administrator may deny frivolous or insubstantial requests for a hearing. However, if a substantial request for a public hearing is made by June 29, 2007, EPA Region 5 will hold a public hearing. If EPA Region 5 does not receive a timely and appropriate request for a hearing and the Regional Administrator does not elect to hold a hearing on her own motion, this determination shall become final and effective on June 29, 2007. Any request for a public hearing shall include the following information: the name, address, and telephone number of the individual, organization, or other entity requesting a hearing; a brief statement of the requesting person's interest in the Regional Administrator's determination and a brief statement of the information that the requesting person intends to submit at such hearing; and the signature of the individual making the request, or, if the request is made on behalf of an organization or other entity, the signature of a responsible official of the organization or other entity.

ADDRESSES:

All documents relating to this determination are available for inspection at the following offices: Indiana Department of Environmental Management, Office of Water Quality, Drinking Water Branch, 100 N.
